[crypto] PSA API: introduce platform API for crypto dynamic memory mgmt

Browse Source 
This commit adds two new functions, `otPlatCryptoCAlloc` and
`otPlatCryptoFree`, which provide dynamic memory management for the
crypto subsystem. They are only enabled when
`OPENTHREAD_CONFIG_HEAP_EXTERNAL_ENABLE` is set.
